Question

Given:

Temperature of H₂O = 20⁰C

Pressure = 0.95 atm

Initial Air Volume = 50mL

Final Air Volume = 95mL

Volume of O₂ collected = 95mL - 50mL = 45mL

Total Reaction time = 17mins

Balanced equation for hydrogen peroxide decomposition:

2H₂O₂------ 2H₂ + O₂

Using the Ideal Gas Law (PV = nRT), calculate the grams of O₂ produced in the reaction above(decomposition of hydrogen peroxide). (Hint: solve for n, and then convert moles of O₂ to grams. Watch your units; you may need to convert some of your data into different units.)

Definition Definition Law that is the combined form of Boyle's Law, Charles's Law, and Avogadro's Law. This law is obeyed by all ideal gas. Boyle's Law states that pressure is inversely proportional to volume. Charles's Law states that volume is in direct relation to temperature. Avogadro's Law shows that volume is in direct relation to the number of moles in the gas. The mathematical equation for the ideal gas law equation has been formulated by taking all the equations into account: PV=nRT Where P = pressure of the ideal gas V = volume of the ideal gas n = amount of ideal gas measured in moles R = universal gas constant and its value is 8.314 J.K-1mol-1 T = temperature
